Just curious what you guys are seeing. I have a 120DT with a 40g sump and I was seeing about 1.5 gallons/day evaporation. I recently added glass tops to my display and this took me down to a measly .50 gallons/day evaporation. Easily the best thing I've done to my tank in terms of fighting evaporation needs.

Well, in reality, the A/C has not been running all that much given the temperatures. I imagine a lot if it has to do with the overall HVAC not running as much. I imagine evap rates will increase once the A/C starts to run for longer periods.
Im at two gallons a day on 200 gallons of water. Like Grants mine changes seasonally.
My 75 with a canopy on top is loosing a gallon a day. It's been consistent for the last two weeks as I've monitored it with consideration of using Kalk.
Also considering a 10 gallon ATO or something larger than the 5 gallon jug I'm currently using. Just getting tired of dumping $$$ every week into this box of water...

That seems like a lot, on my screen topped 75g I loose about 16-20oz daily, just set up Hydor smart top offs on both of my tanks, each is feed by a 5g jug that is tied to a float sensor actuated RODI line (never have to fill it). Cost $103 for each tank, never having to manually top opp of fill the ATO...priceless.
I think it's probably a good idea to include tank temps and other things that might affect evaporation.
My 120 stays at 79.3 degrees and the room it's in is usually around 70-74 depending on the season. I have glass tops on the tank and two herbie drains, so almost 0 splashing. I use LED lighting as well. I lose about 0.5 gallons per day in evaporation right now. I'll be curious to see if it changes once the A/C starts running more often.

There are numerous factors that can effect your evaporation rates.
Mine tend to be very high because I have a dehumidifier running 24/7 in the basement with the sump so the air stays dry. I also have a 24" box fan blowing on the sump in the summer(that accounts for probably 5-8 gallons a day alone) but I never need a chiller.
No matter what your evaporation rate is, a good ATO is a life saver.

It's probably because I run 2, 175W MH and have a fan in the top of the canopy. There's also a Radion with a small fan but that's not pulling much air.
I've got a Tunze ATO pump in the 5 gallon jug. A 10 gallon RO reservoir would be perfect for my system!
I was using a 7 gallon Salinity container but I like to be able to see the water level sooo.
